Abstract

La présente invention concerne un système de mesure (6) d’une température corporelle d’un individu comprenant : - une caméra infrarouge (12) ; deux étalons (11, 13) positionnés dans le champ visuel de la caméra infrarouge ; - deux sondes thermiques (16) configurées pour mesurer une température instantanée des étalons (11, 13) ; et - une unité de traitement (15) configurée pour déterminer un coefficient de gain (k1) et un coefficient de décalage (k2) à partir des températures instantanées respectives des étalons (11, 13) et de leur valeurs de température des étalons (11, 13) dans l’image électronique obtenue par la caméra infrarouge et pour appliquer ces coefficients aux valeurs de température associées à chaque pixel de l’image de sorte à obtenir une image corrigée. Figure pour l’abrégé : Fig. 1The present invention relates to a system (6) for measuring a body temperature of an individual comprising: - an infrared camera (12); two standards (11, 13) positioned in the field of view of the infrared camera; - two thermal probes (16) configured to measure an instantaneous temperature of the standards (11, 13); and - a processing unit (15) configured to determine a gain coefficient (k1) and an offset coefficient (k2) from the respective instantaneous temperatures of the standards (11, 13) and their temperature values of the standards (11 , 13) in the electronic image obtained by the infrared camera and to apply these coefficients to the temperature values associated with each pixel of the image so as to obtain a corrected image.
